Maple Grove, MN -- (SBWIRE) -- 03/12/2015 -- The landforms of the world are constantly changing and have an interesting history all their own. So, it becomes necessary to know about the things that shaped the history of the earth and volcanoes are one such thing that played a pivotal role in the origin of the earth. For providing information about the earth, World landforms educates its readers and students about one of the most interesting landforms, i.e. Shield Volcanoes. An individual can gather ample information from the portal about volcanoes. Shield volcanoes are entirely formed from fluid lava. These are large structures and are circular fan shaped in nature and thus look like a shield. Shield volcano formation takes place when pressure is formed due to heating of the gas, raising the magma upward where it explodes. The molten lava through the central vent then comes out.
Readers who are interested in learning about the different types of volcano landforms can get a lot of information on this portal. The online portal is easy to use and provides information in a very structured manner with pictorial illustrations. Besides Shield Volcanoes, the other types of volcanoes a reader can get information about are Composite or Strato-volcanoes, Cinder cones, Spatter cones, Complex volcanoes, super volcanoes and submarine volcanoes. The portal also ensures a one-of-a-kind experience to its readers by keeping its article short yet informative.
Talking about Shield Volcanoes, one of the representatives of World landforms stated, "The interesting fact about shield volcanoes are that they are formed when there are effusive volcanic eruptions with magma flowing out in all directions to form a shield-like shape. They are built of weak viscous basaltic lava. The effusive eruptions allow lava to flow longer distances than other types of volcanic eruptions making larger and thinner sheets of lava. The continuous build-up of the sheets over a long period of time constructs a low broad profile of the shield volcano."
